Top 10 Node.js Projects with Source Code [Beginners to Advanced]

Node.js was launched in 2009. Since then, it has revolutionized app development processes by introducing JavaScript runtime environments, perfect for server-side program creation. As a result of this tremendous innovation of technology and the user-friendly nature of the program itself, Node.js based application development is becoming increasingly prevalent across multiple ecosystems.

These ecosystems include social networking sites and instant messaging platforms. Because of its low memory footprint, Node.js is perfect for creating Node.js projects and using compact devices like IoT gadgets and microcontrollers.

What is Node.JS?

Node.js provides an open-source and cross-platform backend JavaScript runtime environment. When making front-end developments like apps or websites with Node.js, in conjunction with Chrome’s V8 engine, it effectively converts scripts to machine code; this gains speed while being highly effective at scaling up functions.

For applications requiring multiple data streams simultaneously available in real-time (like message services), Node.js’ event-driven mechanics will help you optimize efficiency by unblocking input/output workload management. NPM (Node Package Manager) is a valuable resource for developers who want to enhance their application’s functionality.

With its vast range of packages and modules readily available via Node.js integration, leading corporations like Netflix, LinkedIn, and Uber use it frequently for their backend operations.

Node JS Projects for Beginners

The following are a few node JS projects for beginners.

1. Battleship Multiplayer Game 

Battleship is an online game that can host multiple players. Node.js is implemented on the server side to manage communication among gamers and servers. Communication goes both ways with help of web sockets such as sockets. IO. The game employs JavaScript for its execution, which happens on client- and server-side machines.

Working: Once the game begins and the players have joined, socket.IO broadcasts the updates to each player to ensure they are on the same page. It helps synchronize the game between the client (players) and the server (Node.js backend).

Technologies Required:

Use the following technologies in this application:

• Node.js
• Express.js
• Socket.IO
• Canvas API
• JavaScript

Source Code: Battleship Multiplayer Game

2. Chat App 

You can also develop a chat application that allows multiple users to chat. The best platform for creating applications for instant messaging is Node.js. The Node JS framework can manage anything from sending messages to viewing them, noting the timestamps, and displaying receipts. 

Working: Here, you create a Node.js server with Express.js framework. Integrate socket.IO in your application to facilitate real-time communication between the server and the client. The user connects to the server, establishing a WebSocket connection. When the user sends a message, the server broadcasts it to all connected clients, providing instant updates for all participants.
